Reduce the impact force to keep the roller frame and between the pillars. In the main gear bearing design parameters when changing gear bearing the pursuit of maximum rated load of conventional design methods, reducing the diameter of the roller and increase the number of roller gear, while increasing the roller diameter pillar and pillar holes to increase pillar and the overall strength of the cage. Improvement compared with the previous gear bearing static load rating is roughly equal, dynamic load rating is reduced, is still able to meet the needs of practical work gearbox bearings, and roller weight decreased and gear reducer, reducer bearing rated load, although slightly reduced, but effectively reduces the impact force of the roller holding frame and between the pillars, the pillars extend life, and because the roller diameter decreases, a corresponding increase in the wall thickness of the ferrule can be improved impact resistance reducer bearing. Thus delaying the holder of the expiration time, extending the gear bearing life. To improve the welding strength. Increasing the use of weld puddle forms the steps to strengthen the bond strength; abandon common thread undercut, with smaller threads to achieve a natural transition ending, the force decreases pillar stress concentration and welding parts thread tail. In addition, the roller end corresponding to the end face of the inner frame to maintain optimal design, the first rv reducer, inside and outside diameter of the end face of the miter angle to facilitate the grease into the roller pillar holes, improving pillar and pillar holes roller friction between; reduced cage and roller end contact area, improve the contact properties, to avoid burns caused by excessive friction, the phenomenon of cement. Secondly worm reducer, the welded part of the original pillars of welding hole sink hole to form chamfered to enhance the welding strength, avoid sealing off. Based on the domestic and foreign markets is a prerequisite for the development of high-tech products eternal development. As the market economy more active than ever, nine # Five-Year period, Runchi factory slowdown further increase product development efforts, they are for energy, transportation and infrastructure needs, have developed a compactor, tamping machine, Excavators for assembly required for high-power, lightweight T CJ dedicated coaxial gear reducer; adapt to high bearing capacity mining, underground transport needed to facilitate the construction of DCY gear reducer; adapt steelmaking converter temperature, high load capacity required NBD planetary gear reducer; voyage needed to adapt the ship has inverted, clutch and propeller functions MB series marine gearbox; at the same time, also have developed a mining, lifting, transportation industry big power, big span jobs required ZQA, ZQD series of cylindrical gear reducer; adapt to the speed range of engineering applications needs special conditions jib planetary gear-type continuously variable friction and small size, low noise planetary gear reducer; strong carrying capacity of Hardened reducer; Hardened vertical axis reducer; shaft-mounted reducer gearbox family hundreds of new products. _ Runchi screw lift reducer (certified) _ Zhaoyuan gear provided by the Texas Runchi reducer Limited.
